Since my thesis covers a very specific topic (QM of Retinal's Photoisomerization) I have to divide my Bibliography in two sections:

Essential Bibliography

Further Reading

First I looked up the package biblatex, which I found very useful for this purpose, the only bad thing is that I have to use only LyX (I even searched http://wiki.lyx.org/BibTeX/Biblatex but the procedure described is too tricky).

After consulting the "Additional LyX Features" I searched the package bibtopic and, after following to the letter the description on paragraph 3.1.2, I get this unexpected looking division:

Essential Bibliography

[1] Document...

[2] Document...

Further Reading

[3] Document...

[4] Document...

The problem is that the citation numbering doesn't stop for each paragraph, even if two BibTeX Bibliographies have been generated; maybe it is determined by the absence of an appropriate Bibliography title: since bibtopic removes it, I had to manually re-add that (as a \chapter* or \section*, for instance).

I know that biblatex offers a better result, since the citation numbering is divided properly, but to use this feature I have to switch to TeXworks:

Essential Bibliography

[1] Document...

[2] Document...

Further Reading

[1] Document...

[2] Document...

So can I still use BibTeX (and the related extensions) and be able to generate the same result as biblatex?

P.S.: I apologize fot the possibly bad English and the request itself, because on other forums I've been told to switch directly to biblatex and forget about LyX.

Yes, with BibTeX and LyX it is possible to generate such bibliographies. It is just a setting of an option of the bibtopic package in an indirect way. Its document mentioned the following package option.

sectcntreset
Reset the numerical label for the bibliography items for
each btSect environment to '1'. (The default is continuous
numbering.) Note: This makes only sense when having at most one
\btPrintCited command in all your btSect environments; otherwise,
the citation labels in the document won’t be unique any more! The bad
thing is that you will get no warning from LaTeX about
'multiply-defined labels' in this case – so please use this option
with care.

Add sectcntreset in the field "Custom" of "Document Settings > Document Class > Class options" as a workaround since LyX does not allow to set a package option of bibtopic directly. (If the field "Custom" is not empty then you need to append it with a comma: ,sectcntreset.) Then sectcntreset is applied to all LaTeX packages and hopefully no other package conflicts with having this package option set.
